Abstract: The latest advances in 1550-nm high-speed short-cavity vertical-cavity surface-emitting lasers (VCSELs) are presented. The electrical, optical, and thermal design of these devices is ...

Scientists have known for more than a century that a single-celled organism with no nerve cells — much less a brain — can behave in ways that resemble learning. But those observations only went so far ...

A protist species called Stentor coeruleus appears to navigate by sensing physical shapes — a discovery that suggests even the simplest life forms can exploit geometry to survive. Just one mm long, ...

A giant, single-celled organism with no brain, neurons, or nervous system has demonstrated an advanced form of learning previously thought impossible for a solitary cell. The organism is Stentor ...

Much more difficult is learning to connect different types of stimuli or events, and predicting that one is linked to another. Such associative learning was most famously demonstrated when Ivan Pavlov ...

Bij de naam Stentor denken veel mensen aan de regionale krant, die onder meer in Flevoland, Overijssel en op de Veluwe verschijnt. Minder bekend is dat de krant zijn naam ontleend aan de Griekse ...

Animals use various natural structures as landmarks for navigation. In microorganism habitats, microsediments also form geometrically complex environments. Is there a relationship between the ...
